2 parts: 1) integer array to string 2) string out to a jTextField

Question

I am completely new to Java and Netbeans, but I'm writing my 1st
application that takes a "hex" character input from a jTextField,
then converts it to an "binary" integer array. I then do a lot of bit
manipulation, and generate a new "binary" integer array.
String myhex = jTextField1.getText();
    int len = myhex.length();
    int[] binarray = new int[len*4];
        for (int i = 0; i < len; i++) {
           if (myhex.charAt(i) == '0'){
              binarray[4*i]=0;
              binarray[4*i+1]=0;
              binarray[4*i+2]=0;
              binarray[4*i+3]=0;
           else if (myhex.charAt(i) ==
           // repeat for '1 to 9' and 'a-f/A-F'
           // generate new integer array(s) using various bits from binarrayI realize it might not be the best way to do the
conversion, but my input can be of arbitrary length,
and it is my first time trying to write Java code.
All of the above I've completed and it works...(thanks Netbeans
for making the gui interface design a real breeze!)
So I end up with:
binarray[0]=0 or 1
binarray[1]=0 or 1
binarray[2]=0 or 1
binarray[n]=0 or 1
Where n can be any number from 0 to 63...
I then manipulate the bits in binarray creating a new integer array
and for the sake of expediency let's call it "newbinarray".
newbinarray[0]=0 or 1
newbinarray[1]=0 or 1
newbinarray[2]=0 or 1
newbinarray[n]=0 or 1
Where n can be any number from 0 to 63...
I first need to know how to convert this "newbinarray" integer array to a string.
In the simplest terms if the first three elements of the array are [0][1][1],
I want the string to be 011.
Then I want to take this newly formed string and output it to a jTextField.
string 011 output in JTextField as 011
I've scoured the net, and I've seen a lot of complex answers involving
formatting, but I'm looking for just a simple answer here so I can finish
this application as quickly as possible.
Thanks,

Answer 1

Here's an example, not using NetBeans:
import javax.swing.*;
public class TextDemo extends JPanel
    public TextDemo()
        int[] newbinarray = {0, 1, 1};
        StringBuffer sb = new StringBuffer();
        for (int value : newbinarray)
            sb.append(value);
        String st = new String(sb);
        this.add(new JTextField(st));
    private static void createAndShowGUI()
        JFrame frame = new JFrame("TextDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new TextDemo());
        frame.pack();
        frame.setVisible(true);
    public static void main(String[] args)
        javax.swing.SwingUtilities.invokeLater(new Runnable()
            public void run()
                createAndShowGUI();
}
